I updated the first PDF file, it had pages in it that were out of order. I took the pages from another format, UPDF and converted them. I just placed them out of order.

These are some pages from a book, Elements Of Natural Philosophy copyright 1878 1875.
I thought they were interesting experiments. I like some of the experiments. Especially the glycerin coated box, to get rid of dust.
I liked the invisible perfect mirror too.
I did some experimenting with a virgin computer chip wafer, radiant heat, and reflection of light for lack of a better term. And some of the results were interesting.
Radiant heat passes right through the wafer. Just like quartz. Even though the mirror is facing the radiant heat source. The wafer is cold to the touch, however you can feel the warming radiant heat rays through the wafer. But you cannot see the orange glowing radiant heater. Remarkable.
Here is Newtons disc being spun up. It was an ok experiment. I just thought that I would get less purple then I did from it.
Newton claimed that if you took the spectrum of light in the proportions that the prism displayed. And you created a disc and spun it that, the colors would show a white like look.
It looked kind of lavender to me.

This was the disc you made?
The colours on that disc are not in the right proportion. There should be more red and blue than green and yellow – http://www.lighteducation.com/article.php?sid=72.
Also, the ambient lighting in your experiment wasn’t that good, IMHO. I suggest looking at the spinning disc in broad daylight. It might look whiter then.

You are probably right. I also did an all purple disk as well. And it turned a whitish color as well.
I believe that there is some relation to the slower colors remaining longer, or being more phosphorescent then the blues or purple. I say phosphorescent for lack of a better term.
I believe that the more powerful the light the more white will occur. And this is depressing me. Because that could just be due to the human eye and the slower colors remaining longer.
Or a slight sheen, from the paper. This sheen seems to be able to create a whitish haze over the darker colors. Even the all purple disk.
There is actually more blue then green on the disk. The red I did in small little lines. A lot of them. It is just hard to see them. But they are there. And they should total more then orange and yellow.
Check out the colors created by a long exposure shutter. Of an object first disintegrated, and then allowed to cool. You can note some very interesting things taking place.
Note the order of color, while cooling.
We were taught that the ambient radiation that creates light, is moving fastest while creating violet, slower when creating blue, and then green. And slower still while creating yellow and red.
I was taught that each color from red to violet, removes an increasing amount of energy. And each faster color requires less time to remove an equal amount of energy. The Ultraviolet and x-rays are such a short duration that they are not even noticed or perceived. Yet I was taught that they are there. And I have confidence from some experiments that they are present.
You may have to let this gif animation run through a few times in order to see the color changes. I did this a few years ago. One day I will create a better one with more modern equipment.
For anyone that is interested. The torch on the right of the screen holding the wire. Is charged with straight polarity DC current. Meaning that it is the same as the (-) terminal on a current car battery. This terminal is actually abundant with repulsive electron pressure. Which you can see having its way with the wire, and small specs of molten matter.
Sincerely,
William McCormick

This is an "old hat" as we say. What do these two things have in common? Ah, silicon, right? It is well known that many metals like silicon can be passed by infrared radiation (what you call radiant heat). The sensation of heat is just a reaction of your skin and nerves on the IR radiation. There are even lenses made from silicon for IR radiation. And of course, visible light is (mostly) reflected from metal surfaces. It is all a matter of wavelength and diffraction. The wafer is not a mirror if seen in IR light. |

Hi! You are already giving the correct explanation for the cycling of colours without the need for any "inventive" hypothesis. Planck's law of radiation (together with Wien's law) demonstrates that colour immediately reflects the temperature of a body. Therefore, when you say that the object cools, you get the correct answer. The hotter the bluer, the colder the redder. It's really that easy. The reason lies in the reduction of vibration of the electrons. High temperatures imply a high velocity of electrons, fast electrons emit photons with a higher energy i.e. shorter wavelength. |

I was talking about going from red hot to cool. The color goes, red, yellow, green, blue. And then the normal light is present again.
I am saying that while cooling, the yellow and green are only present for a short period of time. Because a lot of energy is being removed while they are displayed.
They use these same principles in older phosphorus hardening compounds. The phosphorus would turn white hot, and remove a tremendous amount of heat in a short period of time. Surface hardening the piece of metal.
Diamonds also are able to remove heat, by changing the emission to something other then light. Probably Ultraviolet or x-rays.
They say that carbolic acid when allowed to crystallize in large hunks, can explode with unbelievable violence. Because it tries to change the energy created by the fracture, into something else.
Esters of Ethel either are supposed to be some wild crystals as well. Similar to initiating explosives. The claim is that they can detonate and blow limbs off. Old cans of either often form them inside, if they evaporate with the lid closed but not totally airtight.
Sometimes artists use ether for a paint thinner.
